There are two killer features AWS Elastic File System (EFS) needs to deliver:

AWS NFS 4.1 Encryption support

AWS NFS 4.1 Windows Explorer integrated Client or alike

With these two there will be true distributed file system support. This is the last milestone to eliminate the need for disaster recovery (DR) data centers and complicated once or twice a year DR tests. Clients RPO and RTO will be exactly the same as AWS. A true disruption that will save billions across the world as Distributed Document Management Systems (Am I really the first coining DDMS?) take over.

This is my official comment to Mount NFSv4.1 with Windows. I had to comment here since my "account is not ready for posting messages yet" and I do not want to "try again later".

If you are using the same certificate in several servers and just one of them happens to have SSLv2 enabled then all of your servers are vulnerable to the DROWN attack. Do not be misled by results from tools like nmap or sslyze. Better to not have shared keys and make sure of course SSLv2 is not allowed in any of your servers.

As I already posted Amazon Web Services (AWS) is not providing an out of the box solution for such simple thing as monitoring HDD, Memory and CPU usage for Windows. The situation is the same for Linux. That is the reason I went ahead and created a quick plain old bash (POB) script for this matter. I recommend reading the README.md for straight and quick instructions to get it working in less than a minute. The code is in github but for convenience find the linked content below:

Amazon Web Services (AWS) is not providing an out of the box solution for such simple thing as monitoring HDD, Memory and CPU usage. CloudWatch demands still some coding and customization for something that IMO should be provided out of the box. We have Monit for Linux but nothing simple enough for Windows. Prometheus is great but probably overkilling for a small startup. That is the reason I went ahead and created a quick PowerShell script for this matter:
